Aspects of the disclosed technology address the limitations ofconventional pressure monitoring approaches by providing systems,methods, processes, and computer-readable media for remotely monitoringatmospheric pressure conditions. The disclosed technology alsoencompasses software and systems to facilitate the management ofmultiple separate pressure monitoring devices, e.g., differentialpressure sensors. The management system can be configured to communicatewith and to manage separate pressure sensors, for example, that aredistributed at different locations within a common building or facility,such as a hospital, or that are located at different geographiclocations and/or client/tenant sites. As discussed in further detailbelow, management systems can be configured to facilitate tracking ofpressure measurement statistics. As such, the pressure management systemcan be configured to detecting when required pressure differentiallevels are not sustained, and for generating alerts to providenotifications to relevant stakeholders or facilities managers.

SUMMARY OF THE INVENTION

In one aspect, the disclosed technology includes a system forfacilitating the remote monitoring of pressure differentials between twoor more spaces, e.g., indoor areas such as rooms and/or hallways. Thesystem includes a pressure sensor, a wireless transceiver coupled to thepressure sensor, wherein the wireless transceiver is configured fortransacting data with a wireless backhaul gateway, and a microcontrollercoupled to the wireless transceiver. In some aspects, themicrocontroller can be configured to receive a plurality of differentialpressure measurements from the pressure sensor and determine whether totransmit pressure information to a management system based on at leasttwo differential pressure measurements received from the pressuresensor.

In another aspect, the disclosed technology provides acomputer-implemented method for monitoring atmospheric pressureconditions. The method can include a process for receiving a pluralityof differential (atmospheric) pressure measurements from the pressuresensor, and determining whether to transmit pressure information to amanagement system based on at least two differential pressuremeasurements received from the pressure sensor.

In yet another aspect, the disclosed technology provides anon-transitory computer-readable storage medium comprising instructionsstored therein, which when executed by one or more processors, cause theprocessors to perform operations to: receive a plurality of differentialpressure measurements from the pressure sensor, and determine whether totransmit pressure information to a management system based on at leasttwo differential pressure measurements received from the pressuresensor.

FIG. 1 illustrates an example of an automated pressure sensing system100 that can be used to monitor and manage one or more various pressuresensors, such as pressure sensor 111. In the example of FIG. 1, a singlepressure sensor (e.g., sensor 111) is illustrated; however, it isunderstood that pressure monitoring can be performed with a multitude ofpressure sensors, without departing from the scope of the disclosedtechnology. In the example environment of FIG. 1, pressure sensor 111 isdeployed in an indoor environment of building 113 and configured tosense/measure an atmospheric pressure differential between a first room115, and a second room 116. In the illustrated example, pressure sensor111 is affixed to and disposed within a wall 117 separating first room115 and second room 116. In this example, pressure sensor 111 isconfigured to measure atmospheric pressure values in each room, and torecord the differential pressure value. However, in some aspects,separate/discrete sensors may be used to calculate pressuredifferentials, for example, by measuring ambient pressure values andcomparing the same via a wireless communication means.

Differential pressure values recorded by pressure sensor 111 can becommunicated to a management system 104 via a backhaul network thatincludes a wireless (backhaul) gateway 110, cellular network 106, andpublic network 102. The various networks, such as network 102, can alsofacilitate the communications between one or more user devices, such asuser device 112, and/or management system 104.

It is understood that various other networks and/or networking devicescan be used to facilitate communication between pressure sensor 111, andmanagement system 104, without departing from the scope of the disclosedtechnology. Additionally, it is understood that any of the networks usedto transport data between pressure sensor 111 and management system 104can include a mix of private and/or public networks. For example,network 102, cellular network 106, and/or wireless gateway 110 can belocated in separate networks that are part of (or span) one or morepublic or private network/s, such as a Local Area Network (LAN), a WideArea Network (WAN), or a network of networks, e.g., the Internet.

Wireless gateway 110, can be configured to transact data betweenpressure sensor 111, and cellular network 106. Although it is understoodthat any wireless protocol can be used to transmit data between gateway110 and cellular network 106, in some implementation gateway 110 isconfigured to communicate using an unlicensed radio frequency band, suchas WiFi, i.e., any of the IEEE 802.11 standards, Zigbee, i.e., the IEEE802.15.4 standard, or LoRaWAN, i.e., the IEEE 802.11ah standard, etc.Additionally, wireless gateway 110 can be configured to communicate withone or more other wireless relay devices, such as in a mesh networkconfiguration. Although any mesh network protocol can be implementedwithout departing from the scope of the subject disclosure, by way ofexample, gateway 110 may be configured to communicate over a meshnetwork using any of the standards listed under the IEEE 802.11sstandard. It is further understood that various other wirelesscommunication standards can be implemented, without departing from thescope of the disclosed technology.

In practice, pressure sensor 111 can be configured to transmitdifferential atmospheric pressure measurements to management system 104at a predefined frequency, such as every minute, every 5 minutes, or 15minutes, etc. The transmission cadence of pressure sensor 111 may be setas a default parameter or may be adjusted by a user/administrator ofmanagement system 104, such as user 112. In some aspects, thetransmission frequency of pressure sensor measurements may be based onmeasures of power availability, such as based on the power level of aconnected battery. By way of example, the transmission frequency ofpressor sensor measurements may be decreased, e.g., such thatmeasurements are communicated less frequently, if/when it is detectedthat a charge level of a connected battery is low, e.g., below apredetermined charge threshold. Depending on the desired implementation,the charge threshold at which pressure sensor measurement communicationsmay be decreased can be set as a user configurable parameter.

In some aspects, differential pressure measurements may be transmittedby pressure sensor 111 to management system 104 if/when changes indifferential pressure measurements (e.g., between rooms 115, 116) aredetected. As such, transmission of pressure sensor information may betriggered when there are apparent increases or decreases in thedifferential pressure, and/or when the differential pressure falls below(or rises above) a given threshold value.

In some examples, if there are significant changes in temporallyproximate measurements, e.g., indicating a rapid change in the pressuredifferential between rooms 115/116, then the transmission of pressureinformation from pressure sensor 111 to management system may betriggered. The threshold change required to cause transmission of thepressure sensor information may be set by a predetermined threshold,such as 0.20 Pa. By way of example, if the measured pressuredifferential at a first time (e.g., t₁) is 0.70 Pa, and the measuredpressure differential at a second time (e.g., t₂) is 0.40 Pa, thentransmission of pressure sensor information to management system 104 maybe triggered. However, if the measured pressure differential at t₁ is0.70 Pa, and the measured pressure differential at t₂ is 0.60 Pa, thentransmission of pressure sensor information to management system 104 maynot be triggered. Further details regarding the transmission logic ofpressure sensor 111 are discussed in relation to FIG. 3, below.

Pressure sensor data received by management system 104 can be aggregatedand stored to a secured database that can be referenced using a uniqueidentifier of one or more pressure sensors, an identifier of a group ofpressure sensors, and/or an identifier of an owner or stakeholderassociated with one or more pressure sensor units. Further detailsregarding the storage and management of sensor data by management system104 are provided by U.S. Pat. No. 10,581,267, entitled, “AUTOMATEDTESTING OF EMERGENCY LIGHTS,” which is hereby incorporated by referencein its entirety.

FIG. 2 illustrates a conceptual block diagram of a connected pressuresensor 200 that is configured to communicate with a remote managementsystem. Pressure sensor 200 includes a differential pressure sensor 202that is coupled with a battery 204, a transceiver 206, and amicrocontroller 208. Additionally, microcontroller 208 iscommunicatively coupled to a memory 210. Depending on the desiredimplementation, memory 210 may be a disparate component or may beintegrated with microcontroller 208.

In practice, pressure sensor 202 is configured to collect differentialatmospheric pressure measurements as discussed above with respect toFIG. 1. The differential pressure measurements can then be provided tomicrocontroller 208 and stored to memory 210. Additionally,predetermined threshold parameters and/or preset range parameters may bestored to a local memory device, such as memory 210. Transmission ofdifferential pressure information is achieved using transceiver 206, forexample, which can be configured for wireless communication with abackhaul gateway (not illustrated), in order to communicate with aremote management system.

As discussed above, determinations of whether pressure sensorinformation should be transmitted by transceiver 206 can be based onseveral factors. A more detailed discussion of the transmission logicfor connected pressure sensor 200 is provided with respect to FIG. 3,below.

FIG. 3 illustrates an example flowchart of control logic 300 that can beused to determine when pressure information is communicated to a remotemanagement system. Initially, at step 302, atmospheric pressuremeasurements are collected by a pressure sensor, e.g., differentialpressure sensor 111, discussed above with respect to FIG. 1.

At step 304, two or more sets of adjacent measurements are compared todetermine if any change in differential pressure can be detected. Asdiscussed above, changes above a predetermined threshold, such as 0.20Pa, can be registered as a significant change. In such instances, thelogic can advance to step 306 and the new (or most recent) pressuremeasurement information can be transmitted, e.g., to a managementsystem, such as management system 104, discussed above. In some aspects,only the most recently measured pressure data may be communicated. Inother aspects, all pressure data that has been collected since the lasttransmission may be communicated as pressure sensor data.

In some aspects, the predetermined threshold change that must occurbefore data transfer is initiated can be set as a system parameter, ormay be user configured. By way of example, a threshold change indifferential pressure values needed to trigger transmission of pressureinformation may be remotely set by a user or administrator of the remotemanagement system (not illustrated). Additionally, the predeterminedthreshold may depend on other factors, such as the charge level/s of oneor more batteries that supply power to the pressure sensor. In suchimplementations, greater predetermined threshold may be implemented whenbattery charge levels are low (e.g., to reduce a frequency oftransmission), whereas smaller threshold changes may be implemented whenbattery charge levels are high (e.g., to increase a frequency oftransmission). Depending on the desired implementation, thepredetermined threshold may be set to an amount that approximatelycorresponds with the measurement error of pressure sensor, e.g., 0.20Pa. As such, measured changes below the measurement error threshold maynot cause data transmission to occur, thereby preserving battery life ofthe connected pressure sensor device.

In some implementations, differential pressure readings outside of apreset range may trigger transmission of pressure information, e.g., tothe management system. By way of example, if the differential pressurereading is above 5,000 Pa or below 1,000 Pa, then pressure sensorinformation may be sent to the management system. The upper and lowervalues of the preset range may depend on a multitude of externalfactors, including the elevation of the location of the pressure sensor,and/or user configured preferences. As such, the upper/lower thresholdvalues of the preset range may be different in Brooklyn, N.Y. ascompared to Bakersfield, Calif.

In instances where no significant pressure changes are detected, and/orthe differential pressure readings do not fall outside of the presetrange, the logic can advance to step 308, where it is determined if thetransmission cadence (or period) has timed out. In some implementations,the connected pressure sensor can be configured to maintain a minimaltransmission cadence, for example, to initiate communication with themanagement system indicating that the device is stillfunctioning/operational. As such, in instances where no significantpressure change has occurred, but the timeout period has been reached,then pressure measurement information can be transmitted (step 310).Alternatively, if the transmission cadence timeout has not been reached,then the logic can revert to step 302 and pressure measurements cancontinue to be collected by the sensor.

FIG. 4 illustrates a flow diagram of an example process 400 formeasuring and communicating pressure information to a remote managementsystem, according to some aspects of the disclosed technology.

At step 402, the process 400 includes receiving a plurality of pressuremeasurements, e.g., from a differential pressure sensor. As discussedabove, the pressure measurements can be differential pressuremeasurements, e.g., that indicate the atmospheric differential betweentwo areas, such as rooms 115, 116 discussed above with respect to FIG.1.

At step 404, the process 400 includes determining whether to transmitpressure information to a management system based on at least twopressure measurements from among the plurality of collected pressuremeasurement data points. As discussed above with respect to FIG. 3,changes between measured differential pressure values can trigger thetransmission of pressure information to a management system, e.g., ifthe difference exceeds a predetermined threshold (step 406).Alternatively, pressure information may be communicated if it isdetermined that any given differential pressure measurement falls aboveor below a predetermined threshold, i.e., outside of a predetermined (orpreset) range. By limiting transmission of pressure measurement data toinstances where there are significant changes in measurement values orwhere differential pressures are outside of an acceptable (ornormal/average) range, the system can preserve battery resources, i.e.,by limiting data transmission to anomalous data collection events.

In some aspects, other measurement signals may be used to alter thetransmission frequency of pressure sensor information. By way ofexample, a connected pressure sensor of the disclosed technology may beconfigured to detect a charge level associated with a battery coupled tothe pressure monitor, and to reduce a transmit cadence if the chargelevel is below a predetermined charge threshold.

FIG. 5 illustrates an example system in which some aspects of thetechnology can be implemented.
